venting overheating of vtires and particularly where a plurality of tires are employedon a p truck wheel; a It has been found in the use of a plurality of tires on the wheel ofatruck that Where I there is a rubber to rubber contact, rubbing] I of the Contacting surfaces overeach otheras 'ly held between the. tires. a formed between the tires and it will be noted gfio ,thatIt-he ring 7 extends into the recess .8 a a the wheel passesalong the roadway, PElIiJlCll-' larly underheavy loads causes considerable heatto be generated, sometimes to such a v degree ,as' to cause the rubber to melt. This is aggravated by the heavy weights that j I trucks often carry, and the rough roads over.

";Which they mayftraveh It has-also been noticed that the'interior of the tires will quickly rot in viewof the intensity of the'lle t generated at intervals. 1 It is the object of this invention'to elimininate 'the'trouble heretofore occasioned! by providing means for, preventing ortaking' i care of the heat generated by the rubbing together of. rubber surfaces of tires.

A further object is to provide a device Y which'will be unitary in its nature and inexpensive to manufacture.

' j Further ob'ectswlll' appear upon-a study-g Q of the following specification and appended claims taken in conjunction with the draws y-ings which illustratethe invention and in which drawings Figure '1 isa cross section through the tires and felloe of a wheel providedwith two solid rubber tires and which embodies the 3 invention;

. similar to Figure 1 but with three tires instead of two;

. Figure 3 is a further modificati on showing a cross section of a'wheel provided with two 1 tires, an annularring'disposed therebetween and fan or paddle bladesattachedto the ring; and

I Figure 4 is .a side elevation'of a fragment of the ring shown 1n Figure 3.

'kesl of a wheel are attached'to theusual felloe 2, upon whichis mounted the-felloe rim 3 in the usual.

Figure 2 is amodified' form showing a view limitedto the structures shown in the draw p, v I at maybe used. Disposed between the tires 9, 5 7 I f andlOis a fiat metal ring 7 which is easily.

"slidable over the rim 8 and extends entirely;

aroundthe rim, and when-in position istight- A recess 8 is short distance; g i

As the. truck travels, there will a constantrubbing of the tires 9 and 10 upon the metal ring 7 causing it tob'ecome hot-after 'atimeegfifi although theheat thus generated is lessthan would be the case with a rubber to'rubber contact; The ring 7 conducts this heat out into the atmosphere, thereby preventing the heat. from rising to any great intensity. Figure 2 shows a modification where the rings are used with three tires 9, 10 and 11.] 7 4 In Figure 3, a fan 12 isshown as attached to the. ring 7 A fan 12 is shown pear-shaped and issecured transversely the;

. edge of the ring 7. Thus when the tire is revolving rapidly the fan will serve to set in motion cooling currents of-air, thereby pro viding an additional cooling means. "The fan; i 12. may serve the additional "purpose of 'a; traction paddle or blade when the tire sinksz Y into-mud, enabling-the wheelto secure trac- "tion thereby.v

While the invention has been illustrated in what are considered itsbest applications, it?

may have other embodiments Without dc parting from its spirit and is not, therefore,

ings; I v

What 'I claim'is: Y I

The-combination with awheel, of a plu-v ralityof rubber tires secured to metallic rims fittedthereon, and a separate flat metal cool-j ingand air circulating ring between 831(1 I rims andtires, the rubber of said tires, bear-i ing against the opposite sides of the ring, said sides of the ring extending to a distance i outside the contact with 'therubber and having offset air circulating fan portions within the periphery of the tires whereby the sides are exposed to the atmosphere through which heat is radiated.

In testimony whereof I have signed this specification this 22nd day of September, 1922.
